scribed and represented in the following specification and theaccompanying draw- 1ngs, forming a; part of the same.

This invention relates to a Cage for guiding the rolls of a rollerbearing in their movement around the hub; and the ob ect of theinvention is to furnish a new means of securing the rolls in theroll-spaces of the cage. This means consists of a special formation -forthe outer edges of the space- ,bars by which they may be readilyexpanded or upset to retain the rolls in the spaces between the bars.

To Secure the characteristics required in this cage, it is cast of' somemalleable metal like brass, which is adapted to yield under pressure andthus permit the expanding of the space-bars at the line where suchexpansion Would contract the roll-spaces.

The invention will be understood by reference to the annexed drawing, inwhich Figure l is an end view Of 'a hub with a cage thereon, the cagebeing in transverse section at the middle of its length; Fig. 2 is atransverse section of one-half of such a cage with the rolls Securedthereing Fig. 3 shows the cage without the rolls, the view at thelefthand Side of the line Ct-cz is a plan of the half cage shown in Fig.2, viewed from the inside in the direction of the arrow CZ'. At theright-hand side of Fig. 3, the view is an external view of the cage inthe direction of the arrow (1 in Fig. 2.

The cage is shown with heads 72 connected by integral tie-bars c whichare made of Suitable number and proportioned to form roll-spaces (Z forall the rolls with the bars c operating as spacers between the rolls.

The space-bars have concave Sides which produce a widening of theirinner and outer edges, and form sockets or roll-spaces having curvedwalls adapted loosely to fit the rolls and support their entire length.The

rolls are shown as beyond the inner head to contact with a hub 9, and acasing.

To provide for the expanding or upsettin of the space-bars after therolls are 1nserte in the cage, the outer edges of the 'Said bars areprojected considerably beyond the center line of the rolls, and the heador outer edge of each space-bar is widened by the coneavity of itsSides.

The outer edges of the space-bars are So proportioned as to clear therolls when inserting them in the roll-spaces al, but `rnay be upset orexpanded by means of a V-shaped punch or swage t which, when applied toplain cylinders projecting the bar between its edges e can be pressedinto the metal, thus spreading the head of the space-bar as shown at 6in Fig's. .1 and 52, so as to overlap a little upon the Sides of therolls to retain them permanent y.

Fig. 2 shows the effect of thus expanding all of the space-bars in thecage, produeing a contraction of each roll-Space CZ at the outer ends ofthe space-bars, sufficient to hold the rolls loosely in the cage, topermit their free rotation, but prventing .their escape. v

It will be noticed that the expansion of the heads of the space-barsoperates to contract the roll-space throughout its entire length andalso secures the roll permanently in the roll-space, as the heads of thebars cannot by any means be restored to their the roll-spaces.

As the expanded portions of the beads bear upon the rolls throughouttheir entire length, they furnish a very extended surface and thusmaintain the original dimensions of the spaces in which the rolls areinclosed by the expansion of the head.

Having thus set forth the nature of the invention what is claimed hereinis:

1. A cage :For a roller-bearin comprising heads connected by space-barsorining continuous sockets or roll-spaces adapted to admit the rolls andsupport their entire length the outer edges of the space-bars beingextended beyond the center of the roll and proportioned to be readilyupset and.
